vo_gpu: vulkan: add a vk_signal abstraction
This combines VkSemaphores and VkEvents into a common umbrella abstraction which can resolve to either. We aggressively try to prefer VkEvents over VkSemaphores whenever the conditions are met (1. we can unsignal the semaphore, i.e. it comes from the same frame; and 2. it comes from the same queue).
